摘 要:通过2009~2010年在湖南水稻、大麦、小麦、玉米和高粱等几种主要粮食作物上应用万春钛微肥试验,初步肯定了含钛微肥在这些作物上叶面喷施的效果,结果表明:(1)水稻喷施钛微肥每穗总粒数和实粒数比喷自配微肥的处理分别增加3.0%和3.8%,增产150 kg/hm2左右,平均增产7.4%;(2)几种叶面调控剂比较,以含钛微肥增产效果最明显,增产645.4 kg/hm2,增幅37.0%,其次为多效唑,增产424.9 kg/hm2,增幅24.4%,其它产品增产效果不明显;(3)小麦喷施万春钛微肥较喷自配微肥后期成穗率提高5.1%,穗粒数增加3.4%,千粒重增加1.6%,增产235.5 kg/hm2,增幅11.1%;(4)高粱喷万春钛微肥处理地上部干物质总量较喷自配微肥处理增加4.6%~13.7%,平均增加10.8%,籽粒产量也明显增加3.9%~7.9%(平均6.0%)。The field experiments that applying Wanchun titanium contained trace-element fertilizer to several kinds of grain crops (rice, barley, wheat, maize and sorghum) were carried out in Hunan province from 2009 to 2010, which had initially affirmed the effects of spraying titanium contained trace-element fertilizer to the leaves of these crops. The results showed that (1) Compared with treatment of seff-made trace element fertilizer, the total grain number per panic!e and the solid grain number of rice with treatment of spraying titanium contained trace element fertilizer all increased by 3.0% and 3.8%, respectively, the yield increased around by 150.0 kg/hm2 with average increasing rate of 7.4%. (2) Among several kinds of foliar regulator, the titanium contained trace-element fertilizer had the most obvious yield increasing effect, which increasing yield by 645.0 kg/hm2 with amplitude of 37.0%, and the PP333 also had great yield increasing effect, which increasing yield by 424.5 kg/hm2 with amplitude of 24.4%, the other products had no obvious yield increasing effect. (3) In comparison with treatment of self-made trace element fertilizer, spraying Wanehun titanium contained trace-element fertilizer to wheat can increase spike rate in late period by 5.1%, increase grain number per spike by 3.4%, enhance 1 000-grain weight by 1.6%, and increase yield by 235.5 kg/hm2 with amplitude of 11.1%; (4) Compared with treatment of self-made trace element fertilizer, spraying Wanchun titanium contained trace-element fertilizer to sorghum can increase total dry matter by 4.6%-13.7% (average 10.8%), and obviously increase grain yield by 3.9%-7.9% (average 6.0%).
